Dennis DeMartin is accused of misconduct. Goodman's attorneys say he lied to become a juror, not telling the court about several things during jury selection: His wife's own DUI, her alcoholism that he claimed ended their marriage and the fact that his daughter was once the victim of a violent crime.

Monday, DeMartin answered questions from the judge, and then from lead attorney Roy Black and prosecutor Sherri Collins. At times during Black's interrogation, the exchange became contentious, but DeMartin had trouble sharing some specifics, citing a bad memory.

"I'm just telling you that with my mind the way it is, I can only concentrate on one thing at a time," he said. "It's so bad that I have to put (notes on) my front door every day where I'm going because I don't remember in the morning where I'm going."

The defense said DeMartin even talked about the DUI with his ex-wife during the trial, and wrote about it in a book he published after the trial that ended with a conviction of Goodman, the Wellington millionaire and founder of the International Polo Club.

Goodman is serving his 16-year sentence currently at his home as he awaits appeal of his conviction. His 2010 crash killed recent college graduate Scott Wilson.
